Inaccuracy in cities has been the persistent and lingering problem for GNSS, engendering many attempts at a solution and revealing deeply embedded difficulties. This article provides an overview of the Google solution, the rollout in Android phones, and before/after results.
When most were focused on the transition of power in the White House, the day before the Inauguration and the very last day in office for the outgoing party, the FCC denied a petition to stay (delay) the Ligado Networks deployment of a low-power nationwide network interfering with the GPS signal.
The European GNSS Agency (GSA) together with the European Commission has published an Information Note on the Galileo High Accuracy Service, providing an overview of the main characteristics of the service
